My dyson V6 cordless is only working intermittently when in the pick up position - when the stick is upright it works all the time.

SOURCE: Dyson DC07, too much suction...?

have you checked that the roller is turning when the vacum is not in the upright position as ther are 2 belts 1 from the motor to the clutch and 1 from the clutch to the roller if the clutch belt breaks you will find it hard to push because the roller is stopprd.... lie the machine down on its side with the vacume in the open position not upright and check if the roller turns it should only stop when in the upright position. PLEASE MIND YOUR FINGERS.

SOURCE: No suction in upright position

Check the adapters at the bottom. They're supposed to move cleanly when you lower the handle. It's pretty obvious if there's an air gap when you lower the handle, and you should hear the suction in the air gap.

And...call Dyson...their support is great!

I had the same issue and solved it easily.My experience is the same as the March 6th response/ When you push your foot onto the base and then recline the handle, use your toe to gently push the very front of the base down closer to the carpet. This creates a much stronger seal and suction and picks up every bit of dirt easily. If i do not do this extra step the suction is much much less. I tried an experiment with sand that I poured onto my carpet. Initially, I went over the sand 4 times and the dyson 07 would only pick up 50 percent of the sand. I then poured more sand onto the carpet, and this time pushed the front lip down so it was contacting the carpet. This time only two passes were needed to completely **** up all the sand. Not sure why this is not in the manual but it really works. Good Luck!

SOURCE: shuts off in upright position and spitting dirt back out

it is a blockage. Dyson cuts off in this case to prevent overload. Also leaking dirt indicates blockage. Strip everything out you can. Remove foot plate on base and check for hair or fibre blockage. it may be small and in an odd place.. seek and ye shall find. If not, return to dealer for service. Good vacuum though.

This turns out to be an easy fix.

First, get some graphite lube.

Lay the vac on it's 'face'.

1) On the underside of the vacuum, there is a 1/2" wide 'groove" in the motor housing, that runs up the centerline of the machine. Follow this groove from the front of the machine towards the back. As you follow it 'up' into the machine, the groove will 'end'. Just past this point there will be a small black plastic piece with little 'ears' that is resting in another groove that continues just past the point where the first groove ended. This is the upright position lock that isn't releasing. (I've painted the 'ears' red in the attached photo)

2) Using a screwdriver, or butter knife, etc, gently lift this piece out of the groove. The vacuum head should now easily tilt down like it should.

3) Flip the vacuum over onto it's 'back' and you will be able to see the grooves, now visible on the front of the lower head. Apply the graphite to the smaller (upper) groove and try working the unit in and out of the upright position several times to work the graphite into the locking mechanism
